/**
 * Handle the special case error indicating that a second-factor is required for
 * authentication.
 *
 * There are three cases we need to handle:
 * 1. User's primary second-factor device was SMS, OTP was automatically sent by the server to that
 *    device already. In this case we should just prompt for the SMS OTP (or backup code), which the
 *    user should be receiving shortly. We should give the user a way to cancel and the prompt and move
 *    to case 3 below.
 * 2. User's primary second-factor device is authenticator. In this case we should prompt for authenticator
 *    OTP (or backup code) and also give the user a way to cancel and move to case 3 below.
 * 3. User doesn't have a primary device or doesn't have access to their primary device. In this case
 *    we should show a picker of the SMS devices that they can have an OTP code sent to, and when
 *    the user picks one we show a prompt() for the sent OTP.
